flat-d innovations"Boxers are not the best underwear to wear when using a Flat-D. They do not hold the FLATULENCE DEODORIZER up close to the buttocks. We suggest using our double-sided tape to secure the unit to the boxer. Then when you feel the urge, either sit down or pull up your pants so the unit will cover the area of the gas release."madamjujujive at 11:15 pm
